Improved vertical windlass



PATENT FFICE.

CHARLES PERLEY, OF NEW YORK, N. Y.

IMPROVED VERTICAL WINDLASS.

Specification forming part of Letters Patent No. 38,408, dated May 5, 1863.

To all whom it may concern.-

Be it known that I, CHARLES PERLEY, of the city and State of New York, have invented, made, and applied to usev a certain new and useful Improvement in Vertical Windlasses 5 and I do hereby declare the following to be a Vertical windlasses have heretofore been4 made in which the chain-wheel or heaver is driven by gearing from below, as shown in Letters Patent granted to me and reissued. In this instance the three vertical shafts, being on the line, or nearly so, oi' each other, the introduction of a capstan between the two chain-heavers causes them to be at a greater distance apart and occupy space transversely ot' the vessel, which is often a great inconvenience in the sharp bows of vessels. Y

The nature of my said invention consists in arranging the vertical shafts of the capstan and the chain-heavers in a triangular position, in order-that the heavers may be brought nearer together transversely of the vessel, and in so doing I am enabled to introduce two speeds, so that the chain-beavers can be sotated with more or less power in proportion to the motive power, and the power-capstaus are much more efficient in consequence of this provision.

In the drawings, a is a metallic boX of a three-sided form in its general outline. b is a cover over a portion of the box, and c is a cover over the other portion of the box, which latter is raised above the former, as represented. v

d is a capstanhase or pawl-bed with a groove receiving the balls c, upon which the capstan f rests. t' is the shaft of said capstan, and h is the handspike-head.

The shaft t' is to be polygonal at the parts 5, 6, 7, and 8, and turned down cylindrical at the parts 1, 2, 3, and 4.

When the shaft stands in the position shown in Fig. 1, the squares 7 and 8 take square holes in the pinion k and rotate the same as the capstan is revolved in either direction by the handspikes. The pinion k gears into an intermediate wheel, l, on a stud, w, that takes the wheel m on the shaft o, that in turn takes the wheel yn on a second shaft, o'. These shafts 0 and o carry the chain wheels or heavers p and power-capslans q, provided with the pins q and bearing-blocks r, as in aforesaid patent.

The wheel n gears into a pinion, u, on a stud or shaft, y. This pinion is twice the thickness of the pinion Z, in order to gear into the wheel t on the shaft t', above the pinion lr. This wheel .la will always rotate with this train of gearing in the opposite direction to the pinion lc, and to allow ot' this rotation I form a hollow circular space, 1l, in o in order that the square part (i of the shaft t' may revolve in this space, and the wheel c itself revolve around the shaft i. Vhen this windlass is in the position shown, the power applied to the capstan frotates the shaft t', and by the square parts. 7 and 8 rotates the pinion 7 and gears l, m, and n, giving motion to the power-capstans q and chainvheavers p for drawing in the chain or chains when rotated in the direct-ion of the arrows; or when rotated in the opposite direction the chainmay be given out or permitted to run out by its own weight it the coupling to the chain-heaver be disconnected by raising the power-capstan q, (as in aforesaid Letters Patent.)

ln consequence of the pinion k being smaller than the wheels m and n, the capstan f has to be rotated, say, four times to one rotation of the chain-heaver; but as the wheel c is much larger than the pinion 7c, when that is connected to the capstan f said capstan will only have to be rotated, say, twice for every revolution of the chain-beaver, and the power in each instance will be in proportion to the speed.

In order to disconnect the pinion k and connect the pinion or wheel c, I have only to lift the shaft t', which may be done by any convenient means at the time the square holes in the respective wheels coincide', (which is easily determined by a slight movement given to the capstan.) As the shaft t' is raised the square parts 6 and 7 take the square holes in e at each side of the circular recess 11, while the pinion 7c is entirely disconnected by the raising of the square part 7 and the square S, coming within a circular recess, Il, in la. The raising or lowering of this shaft t is to be effected by such devices as might be the most easily applied. I have, however, shown a pinion, w, on a shaft, z, turned by a handle or lever outside the capstan, said pinion taking the teeth l2 in fi. and when the shaft fi is raised the pinion is kept from turning, so as to sustain the shaft by pushing the shaft z farther into the capstan, when the square 13 enters a square hole and retains the shaft i in its elevated position.

It will. be apparent that I thus obtain two different speeds according to the work to be done. It is necessary, however, that when the speed is changed the pawls g should be thrown over and the capstan revolved in the opposite direction in order that the heavers p may be revolved in the same direction as before. In consequenceof this arrangement of gearing all the parts turn whenever the capstan is rorated, so that nothing can rust fast by remaining stationary.

I have shown in Fig. 4 a slight modification ofthe device for coupling the pinion k or c with the shaft i. rlhis device is particu larly adapted to a vertical windlass in which the capstan is above upon the t'orecastle-deck. In this arrangement I make use of a square shaft, t', upon which is a round sleeve, 14, having a coupling square, 15, atits lower end, taking either the pinion k or the pinion o. lis a pin by which the coupling may be sustained, as shown, or be held down in its place when the coupling takes 7c.

The triangular shape ofthe base of my vertical windlass occupies but little room, and is much more rigid than an oblong shape and better adapted to receiving the strain of the chain cables, and the elevated portion c of said box allows the double gearing to be intro duced without raising the chain-wheels higher than heretofore usual.

Vhat I claim and desire to secure by Letters Patent, is-

l. Arranging the shaft to which the motive power is applied and the vertical shafts carrying the chain-beavers in a triangular position, so that the said heavers may be brought nearer together transversely ofthe vessel, as set forth.

2. The combination of two pinions or wheels, 7c and fv, with the gearing of the vertical windlasses, when said wheels 7c and n are of different sizes, and fitted in such a manner as to be connected to or disconnected from the motive power, substantially as specified, in order that the vertical windlasses may receive a faster or slower movement from the motive power, as set forth.

8. The construction of the coupling squares V on the shaft z' and the recesses in the respective wheels k and n, whereby one wheel is coupled and the other uncoupled by an endwise motion given to the said vertical shaft i', as specified. v

4. The arrangement of the pinion fw and shaft a for raising and lowering the shaft t', as specified.

5. Constructing the box or base of the ver# tical windlass containing the gearing of a triangular shape in its general outline in order that the said base may occupy but little space and more iirmlv sustain the strain of the chain cables as specified.

6. In combination with a chain-beaver titted in such a manner that it may be rotatedy from below or disconnected from the motive power, double gearing for communicating a fast or slow motion to such chainheaver,sub-`
